There is a thick salt bed in Cambrian in the periphery of Hetianhe gas fields, and under which the dolomite reservoirs develop well. Besides Yuertusi Group in Cambrian, Sinian system and Nanhua system may possess important oil source rock. Because of the slippage effect of the salt bed, faults are very difficult to disrupt the salt bed, which leads to the good conservation condition, and a batch of structural traps develop under the salt bed. So, the reservoir?seal assemblage under the salt bed in Cambrian is potential for oil and gas exploration.
